Added graalvm compilation

[Lemap1]

With those new code midifications, when building in standalone mode, it create a native lib and executable using graalvm. Linked to issue #1442.

please do not commit generated files. Add generated folders into .gitignore.

This is too late, so maybe this pull request will be squashed into a single commit to remove commited generated files

[Lemap1]

Yes sorry i realized after doing the PR that i did not managed the files generated on a build. I'm doing commits to solve this.

[Lemap1]

OK it seems to be good, there's no more generated files in the PR @nicolas-f.

[nicolas-f]

is the github action generate the native libraries ?

[Lemap1]

In both release and snapshot modes, the workflow builds the standalone version, so it should also build the native library and executable (at least for Linux, since the action runs on a Linux runner, not Windows).
However, I'm not very familiar with GitHub pipelines. Does the action automatically save the output (e.g., the native library and executable in this case) as artifacts, or should I explicitly add a step to store them?
